behavior therapy a therapeutic approach in which the focus is on the patient's observable behavior, rather than on conflicts and unconscious processes presumed to underlie his maladaptive behavior.
Asexual reproduction is more common in invertebrate animals than in vertebrate animals. Unicellular and multicellular plants can reproduce both asexually and sexually. Common types of asexual reproduction include binary fission, budding, sporulation, regeneration, and vegetative propagation. 2 BINARY FISSION. Binary fission is the simplest type of asexual reproduction. During binary fission, a one.celled organism divides by mitosis to form two daughter cells of equal size. Both the nucleus and the cytoplasm divide equally.
Organisms, both prokaryotes (the archaea and the bacteria), and eukaryotes (such as protists and unicellular fungi), reproduce asexually through binary fission; most of these are also capable of sexual reproduction. Another type of fission is multiple fission that is advantageous to the plant life cycle.ragmentation is a form of asexual reproduction where a new organism grows from a fragment of the parent. Each fragment develops into a mature, fully grown individual. Fragmentation is seen in many organisms such as animals (some annelid worms [Which ones?] , turbellarians and sea stars), fungi, and plants.
